The level of electoral turnout is arguably the most widely monitored form of electoral participation. Consequently, electoral systems have often been cited as having a significant effect on turnout levels even though scholars do not agree on the effects of these complex institutions. Since most previous studies have relied on categorical or dichotomous electoral system indicators, this study utilizes Carey and Shugart’s personal vote index to gain theoretical leverage on other electoral system components. In short, I find that where electoral competition is predicated on party, rather than candidates’, reputations, turnout levels rise. The results of a time-series cross-sectional analysis reveal that the personal vote index significantly influences turnout levels even when controlling for a host of other factors.
